The 15.0-kg double wheel with radius of gyration of 100 mm about O is connected to the spring of stiffness k = 460 N/m by a cord which is wrapped securely around the inner hub. If the wheel is released from rest on the incline with the spring stretched 310 mm, calculate the maximum velocity v_{max} of its center O during the ensuing motion[ [m/s]. The wheel rolls without slipping.

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2
